ADAFRUIT INDUSTRIES, PiTFT Plus with 3.2in Resistive Touch Screen

The PiTFT Plus are a range of TFT LCD resistive touchscreens designed specifically to fit neatly onto the top of a Raspberry Pi.

They are available with 3 screen sizes: 2.8, 3.2 and 3.5 inch.

These TFT LCD touchscreens work with the 2 x 20 connector so will not work with the very first original Pi but do work with all later generation Pi's. They use the high-speed SPI interface on the Pi and can be used as a console, X window port, displaying images or videos. You can also have an HDMI display separately connected.

Four mounting ears can be used to attach the display & Pi to a bezel. They can also be snapped off with pliers if you want it to exactly match the Pi size.

Display current draw is mostly the backlight and at full power, the backlight draws around 100 mA. It uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. GPIO #18 can be used to PWM dim the backlight if you like. All other GPIO are unused. You can connect a 26-pin Pi GPIO cable to it. The other GPIO are broken out into solder pads at the bottom.
